IssueTracker

Enhance @Insert and @Update and allow inserting by a POJO that have only some columns of an Entity.

@Entity
data class User(
  @PrimaryKey id: Long,
  name: String,
  email: String?
)

data class UserName(id: Long, name: String)
data class UserEmail(id: Long, email: String)

@Dao
interface UserDao {
  @Insert(entity = User::class)
  insertWithoutEmail(userName: UserName)

  @Update(entities = User::class)
  updateEmail(userEmail: UserEmail)
}

- The @Insert example above is a bit silly, but it makes sense when you want to leave out columns with default values (b/64088772).
- We probably need a better API to support insertion/update of multiple entities/pojos.
